26、of ASME PTC 1, General Instructions. The following information is based on that document and is included here for emphasis and for the convenience of the user of the Code. It is expected that the Code user is fully cognizant of Sections 1 and 3 of ASME PTC 1 and has read them prior to applying this

27、Code.ASME Performance Test Codes provide test procedures that yield results of the highest level of accuracy consistent with the best engineering knowledge and practice currently available. They were developed by balanced committees representing all concerned interests and specify procedures, instru

28、mentation, equipment-operating requirements, calculation methods, and uncertainty analysis.When tests are run in accordance with a Code, the test results themselves, without adjustment for uncertainty, yield the best available indication of the actual performance of the tested equipment. ASME Perfor

29、mance Test Codes do not specify means to compare those results to contractual guarantees. Therefore, it is recommended that the par-ties to a commercial test agree before starting the test and preferably before signing the contract on the method to be used for comparing the test results to the contr

30、actual guarantees. It is beyond the scope of any Code to determine or interpret how such comparisons shall be made.viiFOREWORDASME Performance Test Codes (PTCs) have long existed for determining the performance of gas turbines units and for gas-turbine-based overall plant performance in electric pow

31、er production facilities. These codes have advised the user to conduct testing of gas turbines and gas-turbine-based plants with inlet conditioning out of service and to correct the results of the test with results of a subsequent test of the inlet conditioning system. Yet users of the test codes we

32、re without a test code to provide guidance of the performance of such a test since a Performance Test Code has heretofore not existed to determine the performance of gas turbine inlet air-conditioning equipment. With the growing use of gas turbine inlet air-conditioning equipment in the electric pow

33、er generation industry, the need for a code addressing gas turbine inlet air-conditioning equipment became very apparent. In response to these needs, the ASME Board on Performance Test Codes approved the formation of a committee (PTC 51) in September 2002 with the charter of devel-oping a code for t

34、he determination of inlet air-conditioning equipment performance. The organizational meeting of this Committee was held in March 2003. The resulting Committee included experienced and qualified users, manufacturers, and general interest category personnel from both the regulated and nonregulated ele

35、ctric power generating industry.In developing the first issue of this Code, the Committee reviewed common industry practices with regard to inlet air-conditioning equipment testing. The Committee was not able to identify any general consensus testing methods, and discovered many conflicting philosop

36、hies, approaches, and performance definitions. For some inlet air-conditioning equipment, correction approaches to standard conditions did not exist. The Committee has strived to develop an objec-tive code that addresses the multiple needs for explicit testing methods and procedures, while attemptin

37、g to provide maximum flexibility in recognition of the wide range of inlet air-conditioning designs and the multiple needs for this Code. This Code was approved by the PTC 51 Committee on November 17, 2010. It was then approved and adopted by the Performance Test Code Standards Committee on December

38、 9, 2010. It was also approved as an American National Standard by the ANSI Board of Standards Review on March 30, 2011.ACKNOWLEDGMENTSThe PTC 51 Committee wishes to acknowledge the contribution of the following individuals to the development of Nonmandatory Appendix A: Keith Khasiak, Joseph Shakal,

45、eating) as they apply to gas turbines in simple, cogeneration, and com-bined-cycle applications.The intent of this Code is to provide results with the lowest reasonably achievable uncertainty consist-ent with the best engineering knowledge and practice in the industry, such that appropriate instrume

46、ntation and measurement techniques and procedures be used to determine the following performance variables, as applicable: performance factor carryover auxiliary consumption (power/thermal) temperature change water discharge water consumption distribution/stratification pressure dropThis Code also p

47、rovides procedures for the calcula-tion of the results, and for the correction of the results to reference conditions, as a measure of gas turbine inlet air-conditioning systems performance.1-2 SCOPEThis Code may be used for in situ testing of inlet air-conditioning systems (cooling/heating) as they

48、 apply to gas turbines in simple, cogeneration, and combined- cycle applications. Cooling systems covered by this Code include evaporative systems (foggers and media-based evaporative coolers) and mechanical/thermal refrig-eration systems. Heating systems covered by this Code include compressor-blee

49、d type systems and heating-coil systems.This Code is limited to gas turbine inlet air-condition-ing systems and does not apply to the following: building heating, cooling, or refrigeration systems gas turbine compressor intercoolers wet compression, overspray, deluge, overfogging, and similar technologies other power plant applications such as air-cooled electrical generators gas turbine performanceIn addition, this Code does not apply to the testing of individual atomizing nozzles.
